-
Estimate VFD Energy Usage:
Apply the new efficiency rating of the VFD system to the same operating hours. -
Example: If VFD efficiency is 95%, then 120 hours * (15 kW * 0.95) = 1710 kWh.
-
Determine Savings:
Subtract the VFD energy usage from the baseline energy usage. -
Example: 1800 kWh – 1710 kWh = 90 kWh savings.
-
Calculate Cost Savings:
Multiply the energy savings by the cost per kWh. -
Example: 90 kWh * $0.10 = $9.00.
